CMP 101 EXAM PREP WITH COMPLETE
SOLUTION
what are application software - =a set of softwares to help with personal tasks and make users
more productive
what kind of problems do application software solve - =user specific problem.
what are downloaded softwares called - =applications
Examples of business softwares - =word processing, presentation, database e.t.c
what are open source software - =softwares whose source codes are available to anybody
What is a source code - =contains instructions written by a programmer specifying the actions to
be performed by computer software
Functions of system software - =it provides platform for installing application software
types of booting - =cold and warm booting
Steps of the booting process - =BPOS²A
bios - =Basic Input/Output System
Post - =Power On Self Test
What takes a particular software /program now and brings another one in - =OS
, what ensures that all applications have fair access to the CPU - =OS
The speed of operation of a processor is dependent on? - =memory
Types of memory - =RAM and ROM
Why is ram usually very limited - =high cost of production
Explain virtual memory - =When the RAM is full, the computer moves data that hasn't been used
recently to a space in Secondary Storage into Virtual Memory
May need to be used when there are too many applications open, or an application is too
memory-intensive (or both)
If we need to read some data in Virtual Memory, we need to move that data back to the RAM,
which takes more time, given how much slower data transfer rates are in Secondary Storage is
than RAM
Using Virtual Memory can make a computer slow to respond, and especially when the apps are
too memory-intensive, since the data is constantly getting back and forth just to keep the
program running.
Extension of ram using hard drive
Mention the 3 types of user interface - =Graphic user interface.
menu driven user interface
command line user unterface
when was windows Vista released - =2007
Why is Unix not popular - =Because it is complex to operate
What kind of user interface does Unix use - =Command line user interface
